- 摘要:
- 为解决管网采用常规干空气干燥方法出现的管网盲端、死角干燥不彻底，干燥后露点多次反弹等问题，改进采用真空干燥技术。陕京管线榆林首站工程，工艺管网在吹扫后采用真空干燥技术取得良好效果，通过对参数整理并绘制干燥系统压力-时间曲线，结合操作过程对干燥效果进行分析，系统地阐述了真空干燥技术的干燥原理、施工流程、干燥效果及施工控制要点。为真空干燥技术在站场施工中的进一步推广应用提供参考。
In order to solve the problem that blind ends and corners of pipeline network cannot be dried completely by using conventional dry air and dew point repeatedly rebounds after drying, improved is the drying process and adopted is the vacuum drying technology for drying pipeline network. In Yulin Gas Compressor Station of Shaanxi-Beijing Gas Pipeline, the vacuum drying technology plays a very important role in instation pipeline network drying. Collected are some important process parameters of pipeline network drying, drawn are pressure-time curves of the drying system, analyzed is the drying effect in combination with the drying process and systematically expounded are the working principle, construction process, drying effect and construction control key points of the vacuum drying technology, which will provide theorial and technical supports for further popularization and application of the vacuum drying technology in compressor station pipeline network drying.
